摘要:

为研究果实转色期植物生长调节剂处理对新疆自育品种葡萄果实品质及果实裂果特性的影响。以新疆葡萄瓜果所选育的优良鲜食葡萄品种新郁、新雅为试材,喷施 5 mg/L GA3+5 mg/L 6-BA,设置转色期及每隔14 d喷施1次(T1)、2次(T2)、3次(T3)3个处理,通过对葡萄果实品质基础指标及裂果率测定,筛选出最佳喷施方案;使用ELISA试剂盒测定葡萄果皮细胞壁组成物质(果胶、原果胶、纤维素、半纤维素)的含量以及PG、PEP、PL、CE等关键酶活性,实时荧光定量PCR技术检测PGPEPPLCE基因表达量的变化。结果显示,T3处理下,新郁、新雅2个品种果糖、葡萄糖组分均显著增加,新郁酒石酸、苹果酸含量显著降低,固酸比显著提升,裂果率分别降低40.7,24.0百分点;该处理下转色后期至成熟期与对照相比,PG、PEP、PL、CE代谢相关酶活性降低,对应相关基因表达量也下降,果胶、原果胶、纤维素、半纤维素细胞壁组分物质含量增加,从而影响果实裂果率。综上,转色后连续3次喷施GA3+6-BA处理果实品质提升,转色后期通过负调控PGPL基因的表达,降低了PG、PME、PL活性,增加了原果胶含量;转色后期及成熟期负调控CE基因的表达,降低CE活性,增加半纤维素含量;原果胶及半纤维素含量的增加,稳定了细胞壁结构,增强了果皮机械性能,降低裂果率。

Abstract:

The purpose is to analysis the fruit quality and fruit cracking characteristics of Xinjiang self-bred grape varieties under the application of plant growth regulator.The table grapes Xinyu and Xinya bred by research institute of grapes and melons of Xinjiang uygur autonomous region were selected as experimental materials,and 5 mg/L GA3+5 mg/L 6-BA were sprayed at the veraison period,setting the veraison period and spraying once(T1),twice(T2),three times(T3)every 14 days.The optimal spraying scheme was screened out by measuring the basic indexes of grape fruit quality and fruit cracking rate.The contents of grape skin cell wall components(pectin,protopectin,cellulose,hemicellulose)and the activities of PG,PEP,PL,CE were determined by ELISA kit,and the relative expression of PG,PEP,PL,CE genes were detected by Real-time Quantitative PCR.At the T3 treatment,the content of fructose and glucose components increased significantly,the content of tartaric acid and malic acid decreased significantly,the solid-acid ratio increased significantly,and the fruit cracking rate decreased by 40.7,24.0 percentage points respectively.Compared with the control group from the late verasion to the harvest period,the activities of PG,PEP,PL and CE metabolism-related enzymes and the expression levels of corresponding related genes decreased,and the content of pectin,protopectin,cellulose and hemicellulose cell wall components increased,thus affecting the fruit cracking rate.In conclusion,the fruit quality was improved by spraying of GA3+6-BA three times after veraison period,at the stage of 100% colored berries,inhibited the enzyme activities PG,PME,PL by reducing PG,PL gene expression,then enhanced the production of protopectin,at the stage of 100% colored berries and the harvest period,inhibited the enzyme activities CE by reducing CE gene expression,then enhanced the production of hemicellulose.While the content of protopectin and hemicellulose increase stabilized the cell wall structure,enhanced the mechanical properties of peel and reduced the fruit cracking rate.
